Kovno Kollel also known as Kollel Perushim of Kovno or Kollel Knesses Beis Yitzchok, was a kollel located in Kaunas, Lithuania. It was founded in 1877 by Rabbi Yisrael Lipkin Salanter when he was 67.

A kollel is an institute for full-time, advanced study of the Talmud and rabbinic literature. Like a yeshiva, a kollel features shiurim (lectures) and learning sedarim (sessions); unlike most yeshivot, the student body of a kollel typically consists mostly of married men. A kollel generally pays a regular monthly stipend to its members.
